Caves of Castilla y León: Hidden treasures beneath the ground
The autonomous community of Castilla y León hides dozens of cavities with high geological, archaeological and cultural value. Some are open to the public with guided tours, while others are protected nature reserves. Below, we introduce some of the most impressive caves in the region.
Llamazares Cave (León): Icy beauty in the heart of the mountains
Located in the Leonese region of Valdelugueros, this cave is famous for its glacial environment and its spectacular set of stalactites and stalagmites. The Llamazares Cave is visited with a guide and offers an immersive experience: a lit walkway takes you through chambers with stone columns, dripping ceilings and an almost magical atmosphere.
- Visits: Guided, with prior reservation.
- Suitable for families and school groups.
